Hey Guys, so I just added my purple tang into my new reefer 525 and I totally had brain fog and forgot that I was suppose to wait till I order my biota yellow tang so that I can add them in at the same time. My question is how late is too late to add the yellow tang? Do I still have time to add it now or will the purple tang already be territorial? my purple tang is about 3 inches. Thanks in advance!
